To all whom it my concern:

Be it known that I, COY GEORGE, a citizen of the United States, residingat Blytheville, in the county of Mississippi and State of Arkansas, haveinvented new and useful Improvements in TnternalCombustion Engines, ofwhich the following is a specification.

This invention relates to internal combustion enginesand comprehends theconstruction making use of a stationary piston arranged Within a sleeveconnected with the crank shaft for reciprocatory movement within thecylinder, the sleeve being designed to provide compression and firingchambers at its opposite ends, whereby every stroke is a power stroke,thus providing for compactness, lessfloorspace and a motor which willdevelop as much power as a two cylinder two cycle engine.

Another object of importance resides in the provision of a construction,wherein the piston is cooled by water circulation, the water passingthrough the piston pin which is in open communication with the waterjacket, means being also devised to allow for the escape of air from thepiston.

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals ofreference indicate similar parts in the several views, and whereinFigure 1 is a side elevation of the engine partly in section.

Figure 2 is a vertical sectional view taken at right angles to Figure 1.

Figure 3 is a view in elevation of the piston removed.

Figure 4 is a similar view of the recipro catory sleeve.

Figure 5 is a view of the crank shaft. Figure 6 is an enlargedfragmentary sectional view of a modified form of the invention.

Referring to the drawings in detail, 10

indicates the crank shaft of the motor, in

Figure 1, andv the water may be drained from the jacket by means of apet cock indicated at 14 in Figure 1. The water pump 15 is arranged atone side of the cylinder and actuated from the crank shaft 16 journaledin suitable bearings 17 of the crank case, and equipped at one end withthe fly wheel 18. The carbureter occupies the space indicated-at 19 inFigure 1. Aplurality of spark plugs 20 are mounted in one side of thecylinder, there being two of these plugs for the respective firingchambers to be hereinafter described. The crank shaft 16 is providedwith counterbalancing weights 21.

Arranged within the cylinder 11 at a point approximately midway betweenthe ends thereof, is a stationary piston 22 sup ported by a pin 23 whichprojects beyond the sides of the piston and received by suitablebearings in the cylinder. The piston is equipped with packing rings 24and is further provided at each end with an extension 25 constitutin adeflector for the gas or combustible 'mlxture admitted to the firingchambers. The piston 22 is arranged within a sleeve 27 of suitablelength to define firing chambers 28 and 29 respectively in the oppositesides of the piston 22. This sleeve is closed at both ends, the upperend being closed by means of a removable head 30 while the lower end 31is positioned an appreciable distance within the sleeve 27. The sleeve27 is associated with the crank shaft by means of a connecting rod 32which has one end arranged within the sleeve immediately beneath thelower end Wall 31 and connected thereto by means of the pin 33.Vertically disposed slots 34 are provided in the sleeve to receive thepin 23 which supports the stationary piston 22. The sleeve 27 is furtherprovided above and below the slot 34 with inlet ports 35 and exhaustports 36. These ports are of course adapted to be brought intoregistration at the proper time with the terminals of the intakemanifold 37 and the exhaust -manifold 38. The space within the cylinder11 above the sleeve 27 defines a compression chamber 39, while the spacewithin the crank case beneath the lower end of the sleeve-constitutes acom-' pression chamber 40. The-cylinder is formed with a passage 41 toestablish communication between the compression chamber 39 and thefiring chamber 28 when the sleeve 27 is in its uppermost position, thecylinder being further'provided with a passage 42 to establishcommunication between the compression chamber 40 and the firing chamber29 when the sleeve is in its lowermost position. Obviously, the inletports 35 of the sleeve are alternately brought into registration withthe respective passages 41 and 42. Similarly, the exhaust ports 36 ofthe sleeve alternately register with the respective terminals of theexhaust manifold 38. The sleeve 27 is also provided with spaced openings43 through which the spark plugs fire at the proper intervals.

In practice, assuming that the sleeve is in the position shown in Figure2, the burnt gases exhaust from the firing chamber 28 through themanifold 38, and the combustible mixture from the compression chamber 39enters the firing chamber 28. The combustible mixture which is conveyedfrom the chamber 39 into the passage 41, is directed against theextension 25 which de fleets the mixture upwardly in the chamber 28.\Vhen the charge now contained in the fining chamber 29 is fired, itdrives the sleeve 27 downwardly thus cutting off com munication betweenthe chamber 28 and the passage 41, and bringin the inlet and exthecombustible mixture is transferred from the compression chamber 40 intothe firing chamber 29 through the passage 42, this mixture beingdirected against the projection 25 which deflects the combustiblemixture in the proper direction and prevents it from mingling with theburnt gases which are being exhausted through the exhaust manifold 38.It is of course understood. that during the down stroke of the sleeve27, the combustible mixture is drawn into the compression chamber 39. Atpredetermined intervals during the down stroke of the sleeve, the sparkplug in the firing chamber 28, stnikes the reviously mentioned chargecontained in the said chamber, thus driving the sleeve in an upwarddirection to the position which it assumes as shown in Figure 2.Manifestly, every stroke of the sleeve is a power stroke, or in otherwords. there are two power strokes at each revolution of the crankshaft. The engine will not only develop as much power as a two cyl indertwo cycle engine, but the arrange- 4 ment provides for compactness, theparts heing readily accessible, while economy in floor space is anotherimportant feature pro vided for by the invention.

In Figure 6 I have illustrated a modified form of the invention wherein50 indicates the cylinder which is provided with the usual water jacket51. 52 indicates the piston which is the same in construction as thepiston 22 above described, the piston Utflllg arranged within the sleeve54 a suitable length to define the fining chambers 55 and 56respectively. The sleeve is of the same construction as the sleeve 27above referred to. Passed through the vertically disposed slots 56 inthe sleeve is a hollow pin 57 which is threaded into the water jacket asshown, the pin being provided with openings 58 adjacent the ends thereofand by means of which communication is established between the waterjacket and the pin at 57. A portion of the pin is arranged within thesleeve is also provided with a plurality of openings 59 so that watermay circulate within the piston. the water circulation being through thewater jacket and pin 57 as will be readily understood. An angularlyshaped pipe including a vertical flange 59' is extended through one ofthe openings 58 of the pin vertically within the sleeve, a horizontallydisposed branch 60 of the pipe being passed through the'pin beyond oneend thereof and-is equipped with a pet-cock or the like 61. The pipe isdesigned to oc-.

cupy a minimum space, and is utilized to permit of the escape of airfrom the sleeve so as not to retard the circulation of water Iin anyway. Otherwise, this form of the invention is the same as that abovedescribed.

While it is believed that from the foregoing description the nature andadvantages of the invention will be readily apparent, I desire to haveit understood that 1 do not limit myself in the details herein shown anddescribed and that such changes may be resorted to when desired as fallwithin the scope of what is claimed.
